Description

Technical Field

[0001] The utility model relates to the technical field of tea polyphenol production and processing, in particular to an internal drying device for tea polyphenols. Background Technique

[0002] Tea polyphenols are the general term for polyphenolic substances in tea, including flavanols, anthocyanins, flavonoids, flavonols, phenolic acids, etc. The content of tea polyphenols in tea is generally 15%-20%. Tea polyphenols have a strong antioxidant effect. Its antioxidant ability is 4-6 times that of synthetic antioxidants BHT and BHA, 6-7 times that of VE, and 5-10 times that of VC. Moreover, the dosage is small: 0.01-0.03% can play a role, and there is no potential toxic and side effects of synthetic substances. Tea elements can protect pigments and vitamins in food, keep the original color and nutritional level of food for a long time, and can eliminate peculiar smells.

[0003] In a tea polyphenol drying device disclosed in the Chinese utility model patent application publication specification CN211462094U, although in the treatment process, general drying is difficult to succeed. There are multiple blowing pipes in the drying chamber, and a heating plate is arranged inside the drying chamber. The heating plate prevents the material from caking and blocking the drying chamber. Using multiple blowing pipes can better dry and achieve the purpose of drying. The structure is simple and easy to use. However, the existing equipment only better dries and achieves the purpose of drying with a simple and easy-to-use structure. It cannot quickly transport tea polyphenols into the drying barrel and has a large extraction force during extraction, resulting in the problem that the feeding head flies around and is thrown out. It cannot solve the problem of how to scrape off the caked tea polyphenols containing moisture on the base plate during the drying process. When the added tea polyphenols are less, the stirrer cannot stir and mix the tea polyphenols at the bottom of the drying barrel. It cannot dry the tea polyphenols in the central part, resulting in moisture in the central part of the tea polyphenols. It cannot recover the tea polyphenols remaining on the inner wall of the drying barrel, on the stirrer, and on the drying scraper. It cannot achieve a vacuum in the recovery box to keep the tea polyphenols in a long-term dry state, which is beneficial for long-term preservation. Therefore, a utility model is proposed to solve the above problems. Content of the Utility Model

[0029] Such as Figure 2 , Figure 3 and Figure 7As shown in the figure, in this embodiment, a feeding component 2 is inserted on the surface of the drying barrel 1. The feeding component 2 includes a feeding shaft seat 201, a feeding pipe 202, a feeding head 203, a first shaft seat 204, a feeding suction cup 205, and a feeding electric valve 206. The feeding pipe 202 is sleeved inside the feeding shaft seat 201. One end of the feeding pipe 202 is sleeved with a feeding head 203. The first shaft seat 204 is inserted on the surface of the feeding head 203. The feeding suction cup 205 is inserted on the surface of the first shaft seat 204. The other end of the feeding pipe 202 is sleeved with a feeding electric valve 206.

By opening the drying electric valve 11 and the recycling electric valve 15, the processed tea polyphenols in the drying barrel 1 are extracted into the recycling box 12 by rotating the recycling air pump 16.After the recovery is completed, by closing the drying electric valve 11, the tea polyphenols are blocked by the air pump filter plate 1201 to prevent them from entering the recovery air pump 16 and causing damage to the recovery air pump 16. The recovery air pump 16 rotates to extract the air in the recovery tank 12. After observing the pressure sensor and making the inside of the recovery tank 12 reach a vacuum, the recovery electric valve 15 and the recovery air pump 16 are closed. Thus, the inside of the recovery tank 12 reaches a vacuum and the tea polyphenols are in a long-term dry state, which is beneficial for long-term preservation. In addition, the tea polyphenols are blocked by the air pump filter plate 1201 to prevent the tea polyphenols from entering the recovery air pump 16 and causing damage to the recovery air pump 16, which increases the service life of the equipment.

Drive the base scraper 403 to rotate by the base motor 402, so that the base scraper 403 rotates on the upper surface of the base plate 404. Drive the drying plate 8 to move up and down in the drying barrel 1 by the drying hydraulic press 7. Rotate the stirrer 10 to stir the tea polyphenols in the drying barrel 1. After drying, discharge and recycle the dried tea polyphenols through the drying electric valve 11.

And the adsorption and fixation through the feeding suction cup 205 avoids the feeding head 203 flying out due to excessive extraction force during extraction. Rotate and scrape the tea polyphenols on the base plate 404 to avoid the tea polyphenols containing moisture caking on the base plate 404 during the drying process and causing waste. Adjust the height according to the amount of tea polyphenols added to the drying barrel 1 to avoid the stirrer 10 not being able to stir and mix the tea polyphenols at the bottom of the drying barrel 1 when the added tea polyphenols are less. And through the stirrer 10 for stirring and mixing, the tea polyphenols are fully dried, avoiding the inability to dry the tea polyphenols in the central part and resulting in moisture in the central part of the tea polyphenols. It can quickly recycle the tea polyphenols remaining on the inner wall of the drying barrel 1, the stirrer 10 and the drying scraper 9 to avoid waste and the mixing of new tea polyphenols and residual tea polyphenols affecting the use during the next use.Thus, a vacuum is achieved inside the recycling bin 12, and the tea polyphenols are in a long-term dry state, which is beneficial for long-term preservation. In addition, the tea polyphenols are blocked by the air pump filter plate 1201 to prevent the tea polyphenols from entering the recycling air pump 16 and damaging the recycling air pump 16, thereby increasing the service life of the equipment.
